Israel says the attack targeted a Hamas command and control centre at al-Aqsa Martyrs hospital and that it is investigating the cause of the blaze but believes it was probably started by a secondary explosion
Hamas command and control centres seem to exist in very large numbers. They are wherever the IDF thinks there may be even as few as one Hamas combatant probably. They don’t care who else they kill.
Or they do it anyway, regardless.
As to being a secondary explosion, they used this excuse before when they burnt people alive in tents.
Stop being so reckless with other people’s lives, or stop lying.
